# Memory backend connection refused

A **Hermes** error and how to fix it. The exact message, why it happens, and the steps that resolve it.

Hermes

```
Hermes: failed to connect to memory backend
Error: ECONNREFUSED 127.0.0.1:5432
```

 **Fix:**

Hermes 1.2+ requires an explicit memory backend. For Postgres/Redis, check that the server is running and the connection string in `hermes.toml` is correct. For SQLite (default), ensure the data directory is writable:

```
hermes doctor          # full diagnostic
hermes memory backend  # shows active backend
chmod u+rwx ~/.hermes  # fix SQLite perms
```
